Copper Mining Process | Information | New Mexico | Basics

Once confirmed as viable, the holes are filled with an explosive compound of fuel oil and ammonium nitrate, which is capable of blasting thousands of tons of ore in a single detonation. Once mined, copper ore is treated to remove copper-bearing material in one of two ways: either through concentrating or by a SX/EW (solution extraction ...

20.1 Metal Deposits – Physical Geology

Looking at copper, for example, we can see that while average rock has around 40 ppm (parts per million) of copper, a grade of around 10,000 ppm or 1% is necessary to make a viable copper deposit. In other words, copper ore has about 250 times as much copper as typical rock.
